1980 年,Hunt 和 Dayhoff (2) 在比较这些抑制剂以及非抑制性蛋白卵清蛋白的一级结构信息的基础上,首次认识到丝氨酸蛋白酶抑制剂抗凝血酶和 AC 蛋白酶抑制剂(也称为 1-抗胰蛋白酶)之间存在家族关系。现在,从 60 多种蛋白质的经典蛋白质序列和 DNA 衍生蛋白质序列数据中得知,这种家族关系延伸至病毒和人类等多种来源以及从血浆到神经胶质细胞等多种位置的蛋白质 (3)。通过对几个成员的 X 射线结构测定,现在认识到一级结构相似性延伸到三级结构相似性,该家族的每个成员共有约 350 个氨基酸的核心结构域 (4-13)。 Carrell 和 Travis 为描述该家族成员而创造的缩写词 (14) 是 SERPIN,代表丝氨酸蛋白质酶抑制剂,尽管某些丝氨酸蛋白酶抑制剂,特别是卵清蛋白、甲状腺素结合球蛋白和皮质类固醇结合球蛋白,尚不清楚是丝氨酸或其他蛋白酶的抑制剂。人们对丝氨酸蛋白酶抑制剂感兴趣的主要原因之一是,其中许多丝氨酸蛋白酶抑制剂在调节重要的生理过程中发挥着关键作用,例如凝血(例如抗凝血酶)、纤维蛋白溶解(例如纤溶酶原激活剂抑制剂1)、补体激活(Cl抑制剂)和炎症(ac蛋白酶抑制剂)。
The first recognition that there was a familial relationship between the serine proteinase inhibitors antithrombin and acproteinase inhibitor (also known as a 1-antitrypsin) was made in 1980 by Hunt and Dayhoff (2) on the basis of comparison of primary structure information for these inhibitors as well as the non-inhibitory protein ovalbumin. It is now known from classical and DNA-derived protein sequence data on more than 60 proteins that this familial relationship extends to proteins from sources as diverse as viruses and humans and from a variety of locations from plasma to neural glia (3). From X-ray structure determinations on several members it is now realized that the primary structural similarities extend to tertiary structure similarities, with a core domain of about 350 amino acids being common to each member of the family (4-13). The acronym coined by Carrell and Travis (14) to describe members of the family is SERPIN, standing for serine nroteinase inhibitor, although certain serpins, notably ovalbumin, thyroxine binding globulin, and corticosteroid binding globulin, are not known to be inhibitors of serine, or other proteinases. One of the main reasons for interest in serpins is that a number of them play critical roles in the regulation of important physiological processes such as blood coagulation (e. g. antithrombin), fibrinolysis (e. g. plasminogen activator inhibitor 1), complement activation (Cl inhibitor), and inflammation (acproteinase inhibitor).
